00:00Assalam-o-Alaikum, This is DC Innovator Orient Kit, 1 Ton, DC Motor in it.
00:08The problem in this is that the compressor is not turned on, but after a long time, it seems that the L8 error occurs.
00:17L8 error occurs when the motor, this motor is also new, this is ours, but the customer has sent this for L8.
00:24In this, the motor shakes a little like this, once or twice, and then it is closed.
00:29Okay, that's all there is to it, and the L8 error is shown.
00:32Now why does this error occur?
00:34The L8 video will be wasted if it is made long.
00:37It comes after a long time, at least after half an hour, after 20 minutes, the error does not come early.
00:43In this, I checked, in this, the IPM is installed here.
00:47There is a lot of difference in reading in IPM.
00:50There is a difference in its low side.
00:54When we check it, see this, you will see the meter, I will keep it here.
01:01Okay, you will see this meter, and both things, see this, together in this.
01:06See this, in this, see this, the reading is proper, see this reading.
01:12Okay, this reading is also not correct.
01:15And see this, the reading is not coming in it, it is short, this circuit is also fine.
01:20The problem is that in this, the low side, there is a fault in it.
01:24Because of this, see this, all these are disconnected.
01:27Okay, see this, these are disconnected.
01:29See this, this is also fine.
01:31The problem with its low side is that, because the 15 volts are coming here, 15 volts are also coming,
01:39okay, 5 volts are also coming, but the speed controller of it, its remaining pulse,
01:45the 6 pulses that come in it, 6, it is not getting that.
01:49Two of these pulses are completely dead, but the other two are bad.
01:54Now, the problem with this is that this controller, its installed controller,
02:00if we remove the IPM and check it, that this IPM is bad,
02:06but the 6 pulses that come in it from behind, the 6 legs of the logic pulse are fine,
02:12whether they are coming or not.
02:14Rest, from here, see this, the UVW, I will make you check it right now.
02:24We check the UVW of this, see this.
02:30See this, it is not showing the short at all, okay.
02:34This is fine from here.
02:36The problem has come, so the problem has come from the low side.
02:40That's why the error of L8 is in it.
02:42Now, we will change its IPM, we will change the IPM,
02:49Inshallah, it will be okay, there is no problem left.
02:52But the main thing in this is that whenever you want to change the IPM,
02:56change its same number.
02:58Rest, there is no problem in this.
